Question

Anaesthetic gas with maximum respiratory irritation

• A. Halothane
• B. Enflurane
• C. Desflurane
• D. Sevoflurane

Answer 1

The Correct Option is C

In the context of anaesthetic gases used in surgery, different agents have varying effects on the respiratory system. When evaluating which anaesthetic gas causes maximum respiratory irritation, it's essential to understand the properties of each:

• Halothane: Known for being gentle on airways, with minimal irritant effects.
• Enflurane: Has some irritant properties but is not typically the most potent in this regard.
• Desflurane: Characterized by high pungency and can cause significant airway irritation, especially at high concentrations, often leading to coughing and breath-holding during induction.
• Sevoflurane: Generally well-tolerated with minimal respiratory irritation, making it popular for inhalational induction, especially in children.

Based on these characteristics, Desflurane is recognized for causing the maximum respiratory irritation among the listed anaesthetic gases, due to its high volatility and pungency.
